1 ROOFlNG-SEAMER.

j j srncrrrcnrrouforming part of LettersPatent No. 251,891, dated January 3, 1882.

i i Application filed June 28,1881. (Model) To all whom it may concern:

Beitknown that we, R0131. J mum and Tiles. QBELDING, of- Waynesburg, inthe county of Stark and State of Ohio, have invented certain new and useful Improvements in Roofing-Seamers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledinthe artto which it pertains to make and use it, reference being had tothe accompanying drawings, which form part of this specification. j

Our invention relates to an improvement in roofing-seamers; and it consists in the combination of two jaws, which are pivoted together by meansof suitable levers and which hold the seam firmly between them, and a third jaw, whichis pivoted to one of theholding-jaws, and which is operated by a series of levers for the purposeof turning the edgeot' the seam over at right angles upon the top of one of the jaws.

It still further consists in providing the second jaw with a flanged slide, whereby the length of the jaw can be increased in either direction, as will be more fully described hereinafter.

The object of our invention is to. provide a tool by means of which the whole seaming of the roof can be accomplished by simply going over each seam twice with the same tool at a different adjustment, and one upon which the workmen will not have to use their feet, and thus endanger their standing upon steep roofs.

Figure l is a side elevation of our invention, Fig. 2 is a similar view of the same, showing it closed. Fig. 3 is a plan view of the seamer complete, showing thejaws open. Fig. 4 is a detail View of one end of thejaw l.

A represents a jaw which is rigidly connected to a lever, B. This jaw has suitably attached to it an adjustable extension, O,which can be moved downward so as to raise the tool and adapt it to the height of the seam, and thus adjust the tool to make the first fold of the seam, and after the first fold has been made adjust it on the jaw so as to lower the tool to make the second told. This extension extends over the lower edge of the jaw, as

which has the jaw E secured to its lower end.

Thisjaw acts, in connection with the jaw A, for the purpose of holding the seam in between the two as the top edge of the seam is about to be bent over.- This jaw is provided with the slide G, which can be moved in either direction so as to make the jaw as long as possible in the direction in which the tool is being used. For the purpose of making this slide movable in either direction, the slots H are cut through it, and set-screws which are passed through from the under side of the jaws are passed through these slots and receive screwnuts upon their upper ends, so that the slide can be moved in either direction when the nuts are loosened, and then tightened in position as soon as the slide has been adjusted.

Hinged upon the upper and inner edge of thejaw A is a third jaw, I, which has the arm J secured toits top edge. To the outer end of this arm is secured a connecting-rod, L, which unites the arm to the lowerend of the pivoted lever N. The upper end of this leverN is connected to the lever A by means of a connecting-rod, 0. When the two levers connected to the two jaws A E are opened outward this third jaw is made to close down inside of the jaw A; -but when the twojaws are pressed together by their levers the third jaw closes downward upon the top of thejaw E, as shown. In using our seamcr the extension is first 'adjustedto make the first fold of the seam, and is then secured in place by means of a thumb-screw or other suitable clamping device. This extension then rests solidly upon the top of the roof and the lever B extends straight upward. When the other lever is moved toward the lever B the twojaws clasp the seam rigidly between them, and the small hinged A, this smalljaw continues the fold of. the seam .on down, and thus presses the turned-over part of the seam tightly against its side. All of the seams have their first fold made while the extension is forced downward so as to raise the tool upward; but when the second fold is to be made the set-screws which clamp the extension in place are loosened, the extension is raised upward so as to lower the tool, and

then the second fold is ready to be made. The jaws are applied to the seam when the second fold is to be made, when the top edge of the seam is bent over at right angles, by simply pressing the two operating-levers which move the two jaws A E together. and then by opening these twolevers the fold is completed. It will thus be seen that the single act of closing and opening the levers completes the Whole operation without the help of another instrument and without the necessity of the workmen having to use their feet in any manner, and thus interfere with their foothold upon a steep roof.

In order to enable the small folding-jaw to better adapt itself to the partially turned down shape of the seam, its ends are made slightly rounding, as shown, so that it will act equally as well upon those parts of the seamwhich are spirally bent as upon another.

Our tool accomplishes by going twice over the seams what usually requires two different tools and four difl'erent operations. The extension may bemade adj ustablebydifterentshaped slots, by hinges, or any other means, as we do not limit ourselves to any particular form of adjustment.

Having thus described our invention, we claim 1. The combination of the two jaws A-E, pivoted together by means of suitable operatin g-levers, with a third folding-jaw,which closes downward against the inner side of the jaw A when the two levers are opened and rises upward as the levers are closed together, and which jaw I is operated by a series of rods or levers which are fastened to the levers B D, substantially as shown.

2. In a roof'seamer, an adjustable slide connected to one of the jaws, whereby the jaw can be extended in the direction in which the tool is being moved, substantially as set forth.

3. In a roof-seamer, the combination of the two jaws A E, pivoted together by means of suitable operating-levers, and provided with an extension and an extensible slide, substantially as specified.

at. In a roof-seamer, the combination of the two jaws A E, pivoted together by suitable operating-levers, in combination with a hinged jaw, which is fastened to the jaw A, and its connecting-rods and levers, for uniting it to the two operating-levers, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
